TP2431U-TR

3PEAK · Operational Amplifier · SOT-23-5

TP2431U-TR from 3PEAK, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 +IN input Non-inverting input of the amplifier; rail-to-rail common-mode range, input current limited to 10mA if it exceeds the supply by more than 500mV.
2 -VS power_in Negative power supply, normally tied to ground, with V+ to V- between 2.2V and 5.5V and a 0.1µF bypass capacitor placed close to the part if not grounded.
3 -IN input Inverting input of the amplifier; rail-to-rail common-mode range, input current limited to 10mA if it exceeds the supply by more than 500mV.
4 OUT output Amplifier output with rail-to-rail swing to within mV of each supply rail.
5 +VS power_in Positive power supply, typically 2.2V to 5.5V, bypassed with a 0.1µF capacitor as close to the pin as possible.
